Why do injection molds need to undergo trial molding? Below, the editor will take you to understand.
The defects of most injection molded products are caused during the plasticization and injection molding stages of the injection molded parts, but sometimes they are also related to unreasonable design. The influencing factors include the type of injection port, the number of mold cavities, position and size, the design of the cold/hot runner system, and the structure of the product itself. Therefore, in order to avoid product defects caused by mold design, we need to analyze the injection mold during production.
After obtaining the test results of the injection mold, the operator usually needs to evaluate the specific situation of the mold again to avoid unnecessary costs and time during the modification process. In most cases, in order to compensate for deficiencies in mold design, operators may unknowingly make incorrect settings because the range of parameter settings required to produce qualified products is very small. Once there is any deviation in parameter settings, it may lead to the quality of the final product far exceeding the allowable error range.
The purpose of trial molding for injection molded parts is to identify optimized process parameters and mold design. Not just to get a good sample. This is very important. Even if factors such as materials, machine settings, or environment change, a stable and uninterrupted mass production environment can still be ensured.
